Dear Q-list members, thank you very much for your notes! That’s great! From a German guy I got the original Q1 plans from 1981 and every time I picked up the roll of paper it’s fell like magic.

Vern, I appreciate your enthusiasm but: Carbon and titanium and prohibitions – oh, my! These planes are made from super-cheap insulation materials sourced from Home Depot and a second-hand

Thrust flanges are prone to cracking after ANY strike, but they don't always fail right away. It's a big unknown WHEN. I've seen a live example that I refused to allow my pilot and friend to fly with.

David.. Eugen is installing a modified B&S Vanguard V2 engine. Structurally I agree with the additional stiffening. My memory of the Onan Q1 I flew years ago was that all things considered the

Eugen, Yes, you understand the plans correctly with regard to the BID. You really should have a PDF of the original plans for reference; the OCR version on the Quickheads site is very well done

Glad you brought that up Sam. I was going to say the same thing. Jay

Chris, Let me know if you want me to calculate your decalage from photos. Decalage will definitely impact how your airplane will fly at different CG loadings. If you want me to do that, please

Continental crankshafts are tempered harder than Lycoming crankshafts. They are less likely to deform in a prop strike when compared to that of a Lycoming crankshaft. There is a familiar saying that

My battery is where Bruce mounted his. Jerry

One of our TriQ 200s had a 9 lb weight way back in the tail. When flown with two people it had and almost uncontrollable PIO! The 9 lb weight was removed and the battery was moved forward to just

It's not just the crankshaft flange runout that requires inspection after a prop strike. Per Continental the engine should be torn down and properly inspected. Sam

Brain I would be interested in the O-200. Please PM me at 251 three 77 five two one six. Victor Taylor Irvington Alabama

I would never ask for a finders fee for helping someone sell their plane or project. Corbin -- Corbin N121CG

Wanted to see if I could get a little finder's fee for this 0-200. Guy is clearing out his hanger and said his 0-200 has around 80 original hours had a propstrike from a ground loop when he was

something over 24 lbs with the rack/hold down.

Jay----------  Great video. I  followed Reg when  I installed the 1.8 turbo in my Dragonfly. 750 hrs airframe and 550 Subaru. Still works great, but you always want more.  I have a video on

Charlie----------  I have as much in the back as I can. The rad is under the belly  as far back as the split line.  I am using a 430 CC amp  17 lb battery installed behind the passenger seat, but

Charlie has a valid point, Chris. I'll have the same issue with Frankenbird so you'll have company with this revision. As Charlie points out.. we don't really NEED a heavier battery for the Corvair

Hi Chris, Not sure I can visualize what you are describing below, but no mind. Maybe after Saturday I will understand. In the meantime, here is a little inspiration video for you. Same plane, same

Great idea, Sam, Chris, and all. Can't wait! That side exhaust looks like a tiny turboprop. :)
